Escape Game: Summer of the Baseball Club is a free iPhone game developed by RINTARO HORI. In this game, you find yourself standing alone in the baseball club room on a summer day. With the sound of cicadas as the only thing you can hear, your goal is to escape the room and retrieve your lost memories.

The game consists of three stages, and your progress is automatically saved. You can play the game for free until the end. To progress, you need to tap on suspicious areas to investigate them. If you have multiple items, you can scroll horizontally through your inventory. By tapping an item once, you can pick it up, and by tapping it twice, you can enlarge it for closer inspection. There may be instances where you can use one item on another while examining them.

Escape Game: Summer of the Baseball Club features music provided by sound effect lab, DOVA SYNDROME, and two specific tracks by 蒲鉾さちこ and shimtone, titled "新緑芽吹く頃" and "夏の眠り" respectively.
